The goal of this project is to improve energy efficiency of industrial crushing and grinding operations (comminution). Mathematical models of the comminution process are being used to study methods for optimizing the product size distribution, so that the amount of excessively fine material produced can be minimized.
The present study considers mainly the third optimization level, i.e. the selection of the optimal set-points of the controller. However, to illustrate the method on a simulated grinding circuit, the fourth level, optimal control, will be also simulated, although this is not the primary objective of the study.
This included the bench-marking and optimization of the SABC comminution circuit, focusing on the primary (SAG mill) and secondary (ball mill) grinding mills, and estimating the outcomes of changes to circuit operating parameters (e.g., feed rate, mill load, ball …

Accordingly, the grinding optimization method can be proposed, that is, after the sequencing of tin grinding for 4 Min, another 4 min grinding is conducted to sort the sulfide ore. This process can alleviate the conflict of cassiterite overgrinding and sulfide ore undergrinding, and the grinding energy can also be utilized most efficiently.
